Abstract: A number of applications for high-resolution image capture and processing operate with data derived directly from the colorimetric values of the image source rather than with video signals. One purpose is to accommodate more flexibly the greater variations in spatial resolution, color gamut, transfer characteristic, and aspect ratio that can occur when the original is film-based, rather than video-camera-based. Another is to allow universal mastering that can deliver the finished content to a variety of destinations—conventional cinema, digital cinema, DVD, and broadcast video—without the need for remastering each one. Several products now exist to support operations in this desirable data form, including disk-based storage of very high speed and capacity, but what has been missing so far has been a suitable mass storage backup device. Data representing high-resolution moving images is extremely voluminous, and the limited capacity and transfer rate of most tape-based storage devices has until now caused backup and restore operations to be a major bottleneck in the workflow.

bio
Dave Bancroft is a member of the Strategic Marketing and Technology team in Thomson Grass Valley Broadcast Solutions, Slough, U.K., where he provides long-term strategic planning services to such product development groups in his company as the Film Imaging and Recording based in Germany and the Camera group in the Netherlands. He is also involved in helping the development of electronic imaging solutions, more generally, for new applications such as digital cinematography and digital intermediate postproduction. Bancroft began his career in the BBC, but left the U.K. to follow opportunities in a wide range of responsibilities from software testing to marketing. Over the next 20 years, these took him to the Middle East, Africa, New York, California, and Germany, as he pursued his career with RCA, Ampex, and Philips Broadcast (later to become part of his current employer, Thomson). Bancroft represents his company in the standards-making activities of SMPTE, where he is a Fellow and chairman of the 123 Image Technology Committee. He is also a Fellow of the Royal Television Society and a member of the BKSTS Moving Image Society.
